The TypeScript compiler converts all paths to use POSIX path separators. When on Windows, this can cause problems when comparing paths from other parts of the build system including the file watching provided by chokidar. The referenced files returned from the TypeScript compiler are now normalized to the native path format to mitigate this problem. This also avoids an issue where the same files but with differing path separators were included in the watch files list on Windows due to the bundler using native paths and TypeScript using converted paths.

…Script are normalized

The TypeScript compiler converts all paths to use POSIX path separators. When on Windows,
this can cause problems when comparing paths from other parts of the build system including
the file watching provided by `chokidar`. The referenced files returned from the TypeScript
compiler are now normalized to the native path format to mitigate this problem. This also
avoids an issue where the same files but with differing path separators were included in
the watch files list on Windows due to the bundler using native paths and TypeScript using
converted paths.
